Domain : [tex]\{1,2,3,4\}[/tex]
Range: [tex]\{2,4,6,8\}[/tex]
Explanation:
It is given that Bev earns $2 a week.
Thus, for n number of weeks, we shall multiply $2 with n.
Where [tex]n=1,2,3,4[/tex] is the number of weeks.
For 1 week, Bev earns [tex]2n=2(1)=2[/tex] ⇒ $2
For 2 weeks, Bev earns [tex]2n=2(2)=4[/tex] ⇒ $4
For 3 weeks, Bev earns [tex]2n=2(3)=6[/tex] ⇒ $6
For 4 weeks, Bev earns [tex]2n=2(4)=8[/tex] ⇒ $8
Thus, we can see that the domain is the number of weeks.
Hence, Domain : [tex]\{1,2,3,4\}[/tex]
Also, the money earned is the range.
Hence, Range: [tex]\{2,4,6,8\}[/tex]
